BALING-PRESS.

T all whom it may concern:

Be it known that I, Ransom Y. MITCHELL, a citizen of the United States,residing at Findlay, in the county of Hancock and State of Ohio, haveinvented a new and useful Balingdress, of which the following is aspecification.

This invention relates to baling presses and more especially to pressesfor use in baling waste paper and the like although the machine isequally as well adapted for baling hay, cotton and other materials.

One object is to provide a baling press having means for automaticallyregistering the number of bales produced, this register ing meansincluding mechanisms whereby it becomes impossible to register more thanone bale during the formation of a single bale and whereby it alsobecomes impossible to prevent the actuation of the register while a baleis being formed.

Vith the foregoing and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings,-l igure 1 is a vertical section through a portion of apress having the present improvements embodied therein. Fig. 2 is viewpartly in elevation and partly in section of said press, a portion ofthe press being removed. Fig. 3 is an enlarged section on line ABFig. 1. Fig. t is an elevation of the parts shown in Fig. 3. Fig. 5 is aview similar to Fig. 3 and showing the relative positions of the partswhen shifted out of normal. positions.

Referring to the figures by characters of reference 1 designates thepress box of the. machine, there being an operating shaft 2 journaledupon the upper end thereof and provided, adjacent one end, with aratchet wheel A lever at is mounted to swing upon the shaft 2 and closeto the ratchet wheel and has a dog :3 pivotally connected to andnormally engaging the ratchet wheel so that, when said lever is swung inone direction, the ratchet wheel and its shaft will be rotated. A pawl.(3 is pivotally mounted on the press box and normally engages theratchet wheel to prevent it from rotating in one direction. The lever 1has a socket 7 at its free end for the reception of a handle 8 and itwill be apparent that, by oscillating Specification of Letters Patent.

this handle, an intermittent rotation of the ratchet wheel and its shaftin one direction will be produced. A hand wheel 9 is secured to theshaft 2 close to the ratchet wheel 3 and may be employed, in lieu of thelever, for rotating the shaft.

Gears 10 are secured to the shaft 2 at op posite sides of the centerthereof and each of these gears meshes with a rack 11 formed upon a stem12. The two stems are parallel and are secured in any preferred mannerto the plunger head 13. This plunger head has parallel flanges 14extending upwardly from opposite edges and parallel with the planeoccupied by the two stems 12. As the stems 12 move together at the samespeed and are connected to the head 13 near the two ends thereof, itwill be apparent that the elevation of one end of said headindependently of the other end is positively prevented. The flanges 1 1prevent either the front or rear edge of said head from being elevatedrelative to the opposed edge. All danger of breaking the stems 12 whenthe head 13 is subjected to uneven resistance, is thus positivelyeliminated, thus rendering the niechanism especially desirable for usein C0111 pressing waste paper and the like.

In order that the bales may be readily tied while in the press, theworking face of the head 13 has dove-tailed grooves 15 formed therein.By providing grooves of this shape, when the material is compressed, itwill not till the grooves to the same extent as where ordinaryrectangular grooves are utilized but, instead, there will always be asufficient space within each groove to permit the ready insertion of thetwisted or looped end of the tie wire.

The front of the press box is closed, at its lower end, by a door 16which is hingedly mounted and adapted to be swung open so as to permitthe completed bale to be re moved from the press. A register controlling wing 17 is hingedly mounted, as at 18, withinone side wall of thepress box and is held normally pressed inwardly into the path of theplunger head, by means of a pin 19 which is slidably mounted in one ofthe frame members 20 of the press box. This pin is preferably located ina metal box 21 and has a stem 22 projecting beyond the box. A spring 23is arranged in the box and around the stem and serves to hold the pin 19constantly in contact with the wing 17 and said wing normally in thepath of Cir the plunger head, as indicated by dotted lines in Fig. l.The stem may be provided with a pawl 2t engaging a ratchet wheel 2.;constituting part of the mechanism of a register .26. This register maybe of any desired construction and it is not deemed necessary toillustrate it in detail. It is merely necessary that the construction ofthe register be such as to positively indicate at all times the numberof bales which have been produced, the said register being operated eachtime the pin 19 and stem 22 are pushed outwardly by the wing 17 duringthe movement of said wing out of the path of the plunger head. It isintended to have the stem 22 concealed within the housing of theregister so as to prevent the mechanism from being tampered with.

The wing 17 is provided, near its free end, with a spring pressed catch27 adapted, when the door 16 is closed and when the wing 17 is shiftedout of the path of the plunger head 13, to spring into a notch 28 formedin the door 16 and thus lock the wing against return movement to itsinitial position until after the catch 27 has been released by openingthe door 16.

In using the press the paper or other material to be baled is placed inthe path of the plunger head and said head is forced downwardly by meansof the mechanism which has been described. The compressed material willswing the wing 17 laterally and, the door 16 is of course closed duringthis operation, the catch 27 will automatically engage the recess 28 andthus hold the wing 1? in its shifted position so that it will not returnto its initial position should subsequent operations of the plunger headbe necessary in order to properly compress the material in the pressbox. hen the wing is shifted laterally in the manner described, the pin19 and its stem 22 will cause the register to be shifted one point andas the wing is held against further movement until. the bale has beencompleted, there is no d2 iger of more than one point being registeredby the machine during the :torn'iation ot a single bale.

In order to prevent the wing 17 from being held out of normal positionby any means, and thus preventing the register from indicatingaccurately the actual num ber of bales produced, means have beenprovided whereby the door 16, through which the completed bale isremoved, cannot be completely opened and closed subsequent to suchremoval without returning the wing to its initial or inwardly directedposition. The mechanism provided for this purpose includes a lever 29fulcrumed upon abracltet 3t) and mounted to swing in a plane parallelwith the bottom of the press. One end of this lever normally contactswith the outer face of the wing 17 while the other end thereof has acatch 31 pivotally mounted thereon and adapted to swing in a verticalplane. This catch has a head 32 extending downwardly from its free endand rounded or beveled as shown, and it; also has a stop lug which bearsdownwardly on the lever for the purpose of limiting the swingingmovement of the catch. A plate 3i is secured to the door 16 at the hingeend thereof and has a curved cam plate extending perpendicularlytherefrom and provided with a curved upper edge which is convexed fromend to end, it being understood that the upper face of the plate isconcaved. This cam plate is so disposed that, when the door 16 is openedso as to permit the removal of the finished bale and to release thecatch 27, cam plate 35 will swing against the catch 31 and cause it toride upwardly upon the concaved upper surface of the plate until thehead of said catch engages the upper edge of the plate. The door 16 canbe entirely opened during this operation. hen it is desired to close thedoor 16 so as to permit material to be properly compressed within thepress, the curved edge of the cam plate 35 presses mitwardly orlaterally against the head 32 and thus causes lever 29 to swing upon itsfulcrum and to press inwardly against the wing 17 so as to cause thewing to assume its initial. or inwardlv directed position. Obviously, itany obv ruction holds this wing against such inward movement, it will beimpossible to close the door 16 and the press cannot be used for balingpurposes. The accurate registration of the number of bales formed withinthe press is thus insured.

In order that the wing 17 may be properly limited in its swingingmovement, a stop strip 36 is pivotally connected to it and has a reducedportion 37 slidably mounted within a guide 38. Shoulders 39 are formedat the ends of this reduced portion and are adapted to move against theguide 38 and thus limit the movement of the wing 17.

Various changes can of course beinade in the construction andarrangement of parts without departing from the spirit or sacrificingany of the advantages oi the invention as defined in the appendedclaims.
